COLLAPSIBLE BED.

Specification of Letters Patent. Application filed August 27, 1910.

Patented Mar. 18,1913. Serial No. 579,314.

Bc it known thaty l, LnoroLD BIR, a sub- Austria-Hungary,

and a resident ot' Vienna. 1n the Empire ot .\ustria-liungarv. haveinvented new and n v x n useful lniprovements in (Jollapslble Beds,

of which the following is a specification.

in which the My invention relates to a collapsible bed in which, inY itscollapsed condition, the mattress frame does not posts. 'lhis result isattained owing to the fact that the -connecting members to which theparts of the mattress frame are pivoted move downwardly along thebed-posts when the bedstead the collapsible cross connections betweenthe members of the mattress frame serve for stretching the mattress.

In accordance with the present invention the mattress is foldable andpreferably folds up automatically when the bedstead is collapsed. ln theconstruction illustrated the mattress, like the collapsible parts of themattress frame, are formed of two independent parts each of whichconsists of a number of longitudinal which can be collapsed, accordionfashion, by spring action.

An embodiment of the invention is illustrated in the which-A Figure 1 isa side elevation. Fig. 2 is a front elevation, and Fig. 8 shows thebedstead collapsed. lThe positions shown in broken lines in Figs. 1 and2 show the intermediate positions assumed by the several parts.duringcollapsing. Fig. 4 shows the sleeve serving for connecting thehorizontal bars of the bedstead. Fig. 5 shows the hinge provided in themiddle of the horizontal longitudinal bars viewed from the middle of thebed. Fig. 6 is a side elevation of a bedstead posts and the mattressframe membersconsist of angle iron. Fig. 7 is a cross section, on alarger scale, on the line A-A in Fig. 6. Fig. 8 shows the bed in planwith the transverse stays l2, 13, removed; the mattress is here shown onthe left hand side with wire meshes, while on the right hand side onlythe longitudinal wires are visible. Figs. 9 and l0 show Separate linksof the mattress to a larger scale.

igs. l1 and 12 show the collapsed bed in side elevation and in planrespectively, and

project, beyond the bed I is collapsed. In this bedstead panels ordivisions accompanying .drawing in- Figs. 13 and 14. show the manner inwhich the mattress is folded.

The pillars .l and 2, arranged in pairsatf the head and foot of the bed,are connected by horizontal bars on which the mattress or the like issecured. Each of these bars "of the mattress frame, two of which runlongitudinally of the bed and two transversely thereof, consist of twoparts 3, et and 5, 6 respectively; the outer ends of each part 3 and 5and 4 and 6 being pivoted to sleeves 7 slidable on pillars l and 2 whilethe adjacent ends of the parts 3, 4 and 5, 6, are hinged together. Thisrenders it possible to bring the horizontal bars in a parallel positionto the pillars of the bed, the sleeves 7 traveling downwardly and thehinges 8 and S), provided at the middle moving upwardly, so that in thecollapsed position'the members of the mattress frame do not projectbeyond the pillars.

To provide for guidance and stiifening of the parts, the longitudinalmembers are connected by coupling rods 10, 11 with the pillars. and thepair of pillars at the head, and at. the foot of the bed, are connectedby transverse stays 12,13, the lower ends of which are also pivoted tothe sleeves 7. As a result of this construction, the vloedstead can befolded both longitudinally and transversely. Finally, in the position inwhich the bed is ready for use the sleeves 7 can be retained by means ofhooks 14 or the like mounted on the pillars.

The longitudinal bars are supported at the middle by feet 15 stitfenedby means of cross bars 16 and pivoted to the hinge 8 (Fig. 5). AThetransverse bars 16 and in particular the hinged parts 5, 6 serve forstretching the mattress transversely as when opened out they extend themattress along its width. `When opened parts 5, l6 are securedautomatically but they can also be secured from collapsing by means ofsome suitable device, such for example as a clamp 17, adapted to be slidover the hinge 9 (Figs. 6 land 8).

The bedstead may consist of tubes (Figs. l to 5) or parts may consist ofangle iron.
